What app does this Symbol represent please.

Hello.
Does anyone recognise this little symbol. Can you tell me what app it represents. It's on the tool bar of a Surface pro.
Thanks.

speaker volume?

If its the multi coloured circle, that looks like google chrome, and the head and shoulders looks like the MN account/profile symbol. Maybe if you are logged on here on google chrome, you have a pm or other notification?

It's Google chrome.

The little person icon means it's a shortcut to someone's personal Google account.

It’s to do with profiles signed in on Google Chrome.

Ah! Thank you very much. i'm a numpty! i never noticed it before.
Thank you all xx
